Best Paint For Outdoor Windows: Expert Guide

Painting the exterior windows of your home is a great way to boost your home's curb appeal and add character to your space. Before you get started, it's important to determine the material of your window frames as this will dictate the type of paint you should use. For wooden window frames, a water-based paint is a good choice. If your window frames are made of vinyl, a specialty paint designed to stick to vinyl, such as Sherwin Williams Alkyd Urethane, is recommended. In addition, if you live in an area with extreme temperatures or high humidity, it is advisable to use a primer to ensure the paint job lasts longer.

Paint types for different window materials

When it comes to painting windows, the type of paint you use will depend on the material of the window frame. Here is a guide to the different types of window materials and the paint that is suitable for each:

Vinyl Windows

Vinyl is a popular choice for window frames due to its low cost and good insulation properties. However, vinyl can discolour or peel over time, so it is important to use high-quality paint to protect these surfaces. Acrylic or latex paint is recommended for vinyl windows, as they offer good adhesion and longevity. Acrylic paint is ideal for hard-to-reach areas, while latex paint is more suitable for larger surfaces. When painting vinyl windows, it is also important to use a primer designed for vinyl, such as Sherwin-Williams' Extreme Bond Primer, to ensure the paint adheres properly and lasts longer.

Wood Windows

Wood windows can add a natural and aesthetic appeal to your home. However, wood requires more maintenance than other materials as it needs to be sealed with paint or finish to prevent rotting and sun damage. When painting wood windows, it is recommended to use a primer first and then a coat of exterior trim paint. You can also apply a cladding of aluminium, vinyl, or fibreglass to the exterior of the wood for added protection.

Fibreglass Windows

Fibreglass is a strong and durable material that is becoming increasingly popular for window frames. It can be painted to match the aesthetic of your home. When painting fibreglass windows, it is important to use a bonding primer designed for tricky surfaces, such as Rustoleum bonding primer. After priming, you can apply a coat of paint specifically designed for fibreglass or vinyl windows.

Aluminium Windows

Aluminium windows are commonly used in commercial buildings due to their strength and durability. However, aluminium is not as effective at insulating as other materials, and it can transfer heat and cold more easily. If you wish to paint aluminium window frames, it is recommended to use a quality exterior trim paint designed for outdoor use.

Fibrex Windows

Fibrex is a composite material made from wood fibres and epoxy resin, offering the look of wood with added durability. Fibrex windows can be painted to match your desired aesthetic. Similar to other window materials, it is recommended to use a primer before applying paint to ensure better adhesion and longevity.

Preparing the window surface

Clean the Window Surface:

Start by thoroughly cleaning the window frames and surrounding areas. Use a mild detergent or a mixture of trisodium phosphate (TSP) and water to remove any dirt, grease, or residue. Rinse the windows with clean water and ensure they are completely dry before proceeding.

Remove Old Paint and Debris:

Use a putty knife or a paint scraper to remove any loose paint, window putty, or debris from the window edges and surrounding areas. Be careful not to gouge or damage the wood while scraping. After removing the majority of the paint, switch to a wire brush to scrub away any remaining paint or putty.

Sand the Window Surface:

Once the majority of the old paint has been removed, use sandpaper or a power sander to smooth out the window trim. Sand the surface until it feels smooth to the touch. This step is important to create a uniform surface for the new paint to adhere to. Remember to wear a dust mask and safety goggles during the sanding process.

Repair and Fill Cracks:

Inspect the window for any cracks, holes, or damaged areas. Fill these areas with exterior epoxy wood filler or use wood putty to patch and repair the surface. Allow the filler to dry completely before proceeding. For larger areas of damage, you may need to replace the wood entirely.

Apply Primer:

After the window surface is clean, smooth, and free of debris, it's time to apply a primer. Choose an exterior primer suitable for the type of paint you will be using. The primer will help the new paint adhere better and create a more uniform finish. Follow the manufacturer's instructions for application and drying times.

Protect Surrounding Areas:

Before you begin painting, make sure to protect or cover any areas you don't want to get paint on. Remove or cover items such as storm doors, windows, light fixtures, and mailboxes. If you have plants or landscaping near the windows, cover them with drop cloths or appropriate materials to protect them from paint splatters.

Remember to take the necessary safety precautions during the preparation process, such as wearing gloves, masks, and goggles when working with chemicals or generating dust. By following these steps, you will ensure that your window surface is properly prepared for painting, resulting in a professional-looking finish.

Painting techniques

Painting the exterior of your windows can be a great way to boost your home's curb appeal and character. Here are some detailed painting techniques to help you achieve professional-looking results:

Surface Preparation:

Before starting to paint, it's crucial to prepare the surface properly. This includes cleaning the window frames with a simple solution of trisodium phosphate (TSP) and water to remove any dirt, grease, or glossy residue. For vinyl windows, a soap and water solution or a mild detergent can be used. Ensure the surface is thoroughly cleaned and rinsed. If there is old paint, use a putty knife to remove loose paint. If the window frame is wooden, use sandpaper to smoothen the surface and inspect for any damage, such as chipped wood or small holes. Fill any holes with an expanding filler.

Priming:

Priming is an essential step in ensuring the paint adheres well to the surface. Choose a primer suitable for the surface you're painting. For wooden window frames, you may need to apply a coat of primer, especially if the wood is unfinished. Vinyl windows also require a bonding primer specifically made for vinyl, such as Sherwin Williams' Extreme Bond Primer.

When painting, use a small angled paintbrush for narrow strips of trim. Brushes with soft-grip handles, such as those from Richard Tools' Mini Master Angular Touch Series, are easy to hold and suitable for all paint types. Start by painting the horizontal pieces of the sash, and then finish with the vertical ones to achieve neater results. If your window frame has a grid, paint it first. Don't worry if you get paint on the glass, as you can remove it later. Work in long strokes, applying the paint in the direction of the wood grain for a smoother finish.

Drying and Additional Coats:

Allow the paint to dry completely before deciding if you need another coat for full coverage. Oil-based paints usually take six to eight hours to dry, while latex paints dry in about an hour. Always follow the manufacturer's instructions for drying times and recommendations for additional coats.

Paint Type and Colour:

The type of paint needed depends on the material of your window trim. For exterior wood trim, use a premium exterior gloss paint, either oil or acrylic. For interior wood trim, a high-quality latex gloss paint is suitable. If your windows are vinyl, use an exterior gloss paint specifically made for vinyl, such as Sherwin Williams' Regal Exterior Low Lustre or Duration Exterior Matte Finish. When choosing a colour, consider using neutral colours that match the rest of your home's exterior. Window trim is often the darkest colour on a home, so consider going a little darker than the rest of your exterior paint.

Paint colours and combinations

When it comes to painting exterior windows, there are a few things to keep in mind to ensure a professional finish. Firstly, it's important to use the correct type of paint. Exterior trim paint is specifically designed for outdoor use and will adhere to common trim materials, lasting a long time.

Now, let's dive into the colour choices and combinations that will elevate the curb appeal of your home.

When selecting exterior paint colours, it's essential to consider your siding, trim, front door, and other elements to create a cohesive and appealing look. Here are some tips and ideas to guide you:

• Neutral Colours: Neutral colours like black, white, tan, taupe, and grey are versatile and pair well with many other paint colours. They can provide an easy match and a timeless look to your home's exterior.
• Darker Trim: Window trim is often painted in a darker colour than the rest of the exterior. This adds depth and contrast to the overall aesthetic.
• Multi-Colour Trim: Don't be afraid to use two or three trim colours. You can set your own rules, such as using a lighter trim on the first floor and a darker shade on the second.
• Light and Dark Combinations: Play with light and dark colours to create visual interest. For example, pair light neutrals like white or beige with darker shades like navy blue or black. This contrast adds drama and elegance to your home's exterior.
• Complementary Colours: Choose complementary colours to make your windows pop. For instance, pair a sage green window with a soft yellow door, or opt for a classic red door with white window trim for a bold statement.
• Monochromatic Scheme: For a sleek and modern look, stick to a monochromatic colour scheme. For example, various shades of grey can be used on the exterior, trim, and door for a stylish and cohesive look.
• Natural Tones: Earthy tones like beige, light blue, and cream create a charming and welcoming exterior. These colours blend well with natural elements like stonework and greenery.
• Bold and Vibrant: If you want your home to stand out, don't be afraid to use bold and vibrant colours. A bright key lime or turquoise front door can be an eye-catching focal point when paired with more neutral siding and trim colours.
• Architectural Style: Consider the architectural style of your home when selecting colours. For instance, a classic colonial home might suit a traditional red brick, white trim, and black shutter combination, while a modern home could benefit from a sleek black-and-white palette.
• Surroundings and Landscape: Take into account the surroundings and landscape when choosing colours. Lighter colours tend to make a space feel larger and brighter, while darker colours can make a space appear smaller. Additionally, consider how your colour choices will complement or contrast with the natural environment, such as surrounding greenery or stonework.
• Vinyl Windows: If you have vinyl windows, it's essential to use the right type of paint and primer to ensure adhesion and durability. Acrylic or latex paint works well on vinyl surfaces, and you can add a bonding primer for extra durability.

Remember, the right colour combinations will not only enhance the beauty of your home but also boost its curb appeal and make a lasting impression.

Safety precautions

Painting the exterior of your windows can be a great way to boost your home's curb appeal. However, it's important to take the necessary safety precautions to ensure the job is done safely and effectively. Here are some detailed safety instructions to follow when painting outside windows:

• Ventilation: When painting outside windows, it is important to ensure proper ventilation to avoid inhaling too many paint fumes. Open the windows and doors of the room to create a cross breeze and improve airflow. If possible, use a fan to circulate the air and prevent paint fumes from building up. Paint fumes can cause dizziness, headaches, and nausea, so it is crucial to work in a well-ventilated area.
• Personal Protective Equipment (PPE): Invest in some PPE, such as goggles, gloves, and a respirator mask. These will protect your eyes, skin, and lungs from the chemicals in the paint. Consider wearing long sleeves and an old hat to protect your arms and hair from any paint splatters.
• Ladder Safety: When using a ladder to reach high windows, ensure it is stable and secure. Follow the manufacturer's guidelines for safe usage. Be careful not to lean too far while on the ladder. It is better to climb down, move the ladder, and climb back up to reach distant spots.
• Surface Preparation: Before painting, clean the window frames thoroughly to remove any dirt, grease, or residue. Trisodium phosphate (TSP) is an effective cleaner for this purpose. Wear rubber gloves, a mask, and goggles when working with TSP and removing old paint. Use a putty knife to remove loose paint and putty from around the window edges.
• Lead Paint Safety: If your home was built before 1978, there is a possibility of lead paint. Refer to the EPA's renovation, repair, and painting program for guidelines on safely dealing with lead paint. It is important to take the necessary precautions to avoid exposure to lead.
• Masking: Protect the glass from paint splatters by using painter's tape or a product like Mask & Peel. Tape can be tricky to work with and may leave residue, so consider using paper strips or a masking liquid applied with a brush. These alternatives are easier to apply and remove.
• Primer: Choose a suitable primer designed for exterior windows, such as Sherwin-Williams' Extreme Bond Primer. A bonding primer will ensure better adhesion and a longer-lasting finish, especially on vinyl windows.
• Paint Selection: Select a high-quality exterior trim paint that is specifically made for outdoor use. Acrylic or latex paint is recommended for vinyl windows as they offer good adhesion and durability. Avoid dark colours on window exteriors as they can absorb too much heat, potentially warping the vinyl.
• Protect Surrounding Areas: Use painter's tape to protect the areas around the windows, such as the siding or other materials on your house. This will help create crisp paint lines and prevent accidental paint splatters.
• Clean-up and Disposal: After painting, clean your workspace thoroughly. Store any leftover paint in a cool, secure place away from heat sources or open flames. Dispose of paint and related materials properly, following local guidelines for hazardous chemical disposal.

By following these safety precautions, you can ensure that your window painting project is completed safely and effectively, resulting in a beautiful and long-lasting finish.
